The elevator stops at 100 floors. At every single one, they come for you. 100 Floors — Don't Let Them In is a fast, tense 3D horror-survival game. You stand inside the lift with a corridor on each side. Zombies, runners, brutes, drowned horrors and worse creep toward your doors — tap the left or right side of the screen to slam that door shut before they reach it. But a closed door is a blind door: doors swing back open on their own, and every floor gets faster. Time your slams perfectly to build streaks and score bonuses. Grab coins from open doorways if you dare. 100 floors across 6 horror stages, 50 unique zombies plus 8 horror breeds, girl/boy survivor select, guided tutorial, power-ups (shield, slow-mo, auto-slam), 3 lives, unlockable lift skins, and a terrifying final boss on floor 100. Free to play, runs right in your browser.
We play using two keys—nothing complicated.
